Officials say a two people have now died and two others have been injured after a suspicious house fire in Mississauga early Tuesday.
A fire broke out at a home on Bromsgrove Road, near Winston Churchill Boulevard and Royal Windsor Drive, at around 3 a.m.
Paramedics initially told Global News two people died but in another update said only one person was pronounced dead.
Three others were also taken to hospital -- an elderly woman with critical injuries and had no vital signs, a woman with serious life-threatening injuries and a man with minor injuries, paramedics said.
In an update mid-morning by Peel Regional Police, they said a second person had also passed away in hospital.
Mississauga Fire Chief Deryn Rizzi told Global News two people were able to self-evacuate before firefighters arrived with one of them suffering significant burn injuries.
When firefighters did arrive, Rizzi said they went into the home and found two people in separate rooms.
A cat and a dog were also rescued from the home, she said. The cat survived but the dog perished in the fire.
"There were some really senior firefighters that have seen a number of different fires, they really described it as high, high heat conditions, heavy smoke, flame involvement," Rizzi said. "This was a fire that was really going. And that's why we can see the significant injuries on the patients."
She also said the fire is being deemed suspicious as there were "multiple points of origin."
Peel Regional Police have been called in to investigate and Ontario's Office of the Fire Marshal has also been notified.
Const. Taryn Young told reporters there are no suspects yet and the identities of the victims will not be revealed as next of kin is still being notified.
"This is a tough day for our firefighters when we lose members of our community in a fatal house fire," Rizzi said.
